' e. A. SHAFFER INTERLEAVED SHEET AND PACKAGE THEREOF Filed July 18, 1929 Patented June 24, 1930 UNITED GLENN A. SHAFFEBJ, OF BAY, VISCONSIIQ', ASSIGNQB 'I'O FORT HOVTARID PAPER COMPANY, OF GREEN BAY, WISCONSIN,'A CORPORATION OF WISCONSIII INTERLEAVED SHEET AND PACKAGETHEBIEOF Application filed July 18,

The device comprises a package of interleaved sheets folded and interleaved in a novel manner, and it is an object of the invention to provide a novel form of interleaf which may be packaged and wherein the withdrawal of a folded sheet from the package will pull out the end of a succeeding folded sheet.

It is a further object of the invention to provide a succession of folded and interleaved sheets folded in Zig-zag form into a package.

Further objects of the invention will appear from the following description when read in connection with the accompanying drawings showing illustrative embodiment of the invention, and wherein: a

Figure 1 is a perspective view of a package partly unfolded to illustrate the form of interleaving.

Fig. 2 is a like view of a portion of two sheets showing a modified form of interleaving.

As shown in Fig. 1, the device comprises a sheet 10'folded upon lines 11, 12, longitudinally thereof and parallel to margins of the sheet to provide tabs 13, 14. The thus formed tabs are interleaved with like tabs of the succeeding sheet as 10 by telescoping together the tabs 13, 14 with the corresponding tabs of the succeeding sheet so that the multithickness of one sheet as 10 lies between the body and tabs of the succeeding sheet.

It is to be understood that each sheet after the first is thus interleaved with the preceding and succeeding sheet in the package.

The thus interleaved sheets are folded into zig-zag form. As shown, each, sheet is folded three times to provide four folded sections and each of the end sections of the fold are interleaved throughout their extent with the end sections of the adjacent sheets.

In the form of the invention of Fig. 2, the sheets are folded once upon a line 15 parallel with the edges of the sheet to form a two-ply sheet comprising the two halves 16, 17, and in this form of the invention the thus folded sheets have their ends enclosed between or have the two portions 1929... semi No. 379,210.

16,17, enclosing the end of the adjacent sheet.

In the form-shown in Fig. 2,'the trailing edge of the sheet 18 is shown as enclosed between the two portions of the-fold of the succeeding sheet as 19.

In this form of the invention as in that illustrated. in Fig. 1, the sheets are formed into a package by a zig-zag fold, desirably a four-ply fold and the interfold extends substantially throughout one of the quarter size sections of the entire sheetat each end of each sheet.

It will be understood that the width of tab provided by the fold of Fig. 1 may be varied to suit conditions as determined by the over all size of the package desired and that the number of transverse zig-zag folds formed in each sheet may also be varied withoutdeparting from the spirit of the in vention. Likewise, the fold of Fig. 2 may he longitudinally arranged to provide a fourply thickness of each sheet instead of a twoply as shown if a shorter resulting package is desired. These and other slight changes may bc'rnide in the physical embodiment of the invention without departing from the spirit of the invention within the scope of the appended claims.

I claim:

1. A package of interleaved sheets comprising, in combination, a plurality of sheets,

each sheet folded longitudinally to provide su 'icrimposed portions, transverse portions of said superimposed portions interleaved with transverse portions of like superimposed portions of adjacent sheets in the package, the thus provided strip of interleaved sheets folded zig-zag to form the package.

2. A package of interleaved sheets comprising, in combination, a plurality of sheets, eacn sheet foldedlongitudinally on parallel lines between the edges and the center of the sheet, transverse portions of the thus formed longitudinal folds telescoping at each end of each sheet after the first with like trans verse portions of adjacent sheets for a portion of the length of each folded sheet and the thus formel strip of interleaved sheets formed into a package.

'3. A package of interleaved sheets comprising, in combination, a plurality of sheets, each sheet folded longitudinally on parallel lines between the edges and the center of the sheet, transverse portions of the thus formed longitudinal folds telescoping at each end of each sheet after the first with like transverse portions of adjacent sheets for a portion of the length of each folded sheet and the thus formed strip of interleaved sheets folded zig-zag to form a package. I V

4. A package of interleaved sheets comprising, in combination, a plurality of sheets, each sheet folded longitudinally to provide superimposed portions, the thus folded sheets folded transversely zig-Zag to provide a plurality of substantially similar sections, the end sections of each thus folded sheet after the first havingthe ends of the longitudinal superimposed portions telescoped with like portions of the adjacent sheets in the package.
